ruby, evaluation multiple conditions in an array
So maybe I have this all wrong, but I'm sure there is a way to do this, say I have a an if
statement, that I want to return true
if all the cond开发者_如何学JAVAitions in an array evaluate as true.
say I have this:
def real_visitor?(location, request, params)
valid_location = [
params['referrer'] == 'us',
params['bot'] != 'googlebot',
5 + 5 == 10
]
if valid_location
return true
else
return false
end
end
How would I evaluate each of the conditions in the array valid_location
, some of those conditions in that array are just pseudocode.
Use Array#any?
or Array#all?
. It's like putting the ||
or &&
operator between all your conditions, but it doesn't do short-circuit evaluation, which is sometimes useful.
return valid_location.all?
You don't need the return
keyword, by the way. I'd leave it out.
